  • Process for dehydrohalogenating aromatic halides
    Patent number: 4925998
    Abstract: Disclosed is a process for dehydrohalogenating an aromatic bromide or iodide by contacting the aromatic halide with hydrogen at elevated pressure in the presence of an alkyl halide-forming compound and a Group VIII metal catalyst.
